To all who/m it may concern:

Be it known that' l, JOSEPH '"B. SoHoriELD,

of the city-of Baltimore and State yof Maryn land, have invented certain lmprovements in Spericles and Eyeglasses, of which the following is a specification.

This -invention relates to an improved clamp for attachingto a lens devoid of a rim, a temple'such as is used in spectacles or the bridge of eyeglasses; and its object is to so construct the clamp that it may be easily applied to the lens and will adjust itself to .the surfaces of the saine, as will hereinafter fully appear.

In the further description of the said invention which follows, reference is made to the accompanying drawing forming a part hereof and in which Figure 'l is a 'face view of a part of a lens to which is applied the improved clamp adapted at. its outer end to receive the bridge not shown. l Fig. 2 is a reverse view of Fig.

l. Fig. 3 is ay section of Fig. 1 taken on the l dotted line :1:--a. Fig. l is a section of l1`ig. 2 taken on the dotted line yy. Figs. 5, 6 and 7 are perspective views of the meinbers of the clamp, the last two illustrating a slight moditication in construction.

Referring now to the drawing, l is a part of a lens ofV rimless eyeglasses, and 2 a plate which in Fig. 6 is shown as having a hole a to receive the end of the stud 3 which is provided with a socket I) into which is inserted one end of the bridge not shown. The bridge is held iii place in the socket by means of the screw c shown only in Figs. 3 and 7.

he plate 2 which is originally made flatJ as shown in Fig. ii is subsequently bent longitudinally into a curve to fit closely against `the edge of the 'lens as shown in Figs. l and 2. At one side the plate 2 has an extension d which is bent down at a. right angle as shown in Figs. 2, 3 and fl to form the fixed member of the clamp in which the lens is held. At the other side nl? the plate 2 are formed the projections c which are separated by the rectangular space 5 is a plate having a conformation corresponding very nearly with the extension (Y, :intl which when in position :is hereinafter described, forms the other and separable member of thegolamp; and its head is provided witli the notches g so as to engage the rejections e. By notchfing the plate 5, it

will be seen that its end is provided withv the head it the edges of which overlap the projections c and thereby serveto prevent the bending of the plate d, and reduce the danger of breaking the lens should pressure be exerted thereon iii the direction indicated by the arrow in Fig. 3. lt will therefore be understood that thevhead h formed by notching the plate 5 as described, performs an important function and is necessary to the proper carrying outof my invention.

By means of the construction shown, the plate 5 can be moved a limited distance toward and from the stud 3, and will adjust itself to the surface of the lens without being detached from the plate 2, or altered in length. passes through the lens the t-wo sectionsor members of the clamp are drawn together and in close contact with the lens.

ltwill be understood that iii applying the clamp toa lens, it is only necessary to lbend the' clamp member ci to make it conform to the surface of the lens, as the other member (plate being loose, adjusts itself to the lens as before stated.

claim as my invention A clamp for the lens of rimless spectacles and eyeglasses, which consists of` a curve( plate which fits the edge of the lens and has at one side thereof a fixed clamping member, and at the other side two projections Upon setting up the screw 9 which' which produce a space or notch between them, combined/with a separable memberv which is notched so as to form an exterior head which bears against the outer face of the said projections and admits of the engagement of lthe two members of the clamp iii the manner described, and a screw which passes through the two members of the clamp and the lens, substantially as specified.
